  • Patent number: 6056726
    Abstract: The present invention relates to intravenous catheter insertion devices which employ a sharp needle to introduce and emplace an intravenous catheter into a body vessel of a patient. The sharp needle end is positioned to extend from within the catheter such that the needle and catheter can be introduced into the body vessel which is pierced by the sharp needle. Following use of the present intravenous catheter insertion device to introduce and emplace an intravenous catheter into a patient's body vessel, the needle is withdrawn from within the catheter and the device is separated from the catheter such that only the catheter remains within the body vessel. The safety intravenous catheter insertion device of the present invention comprises self-contained coupling means for preventing separation of the catheter from the device until the needle is substantially transposed into a safety receptacle to thereby permit the used needle to be safely handled and discarded.
